IMPROVEMENT IN APPARATUS FOR MIXING AND MOLDING ARTIFICIAL FUEL.

Specification forming part of Letters Patent No. 147,665, dated February 17, 1874; application filed September 20, 1873.

To all whom it may concern: I

Be it known that I, EMrLEF. LOISEAU, of Mauch Ghimk, in the county of Carbon and State of Pennsylvania, have invented a new and useful Improvement in Machine for Mixing and Pressing Coal-Dust in the M anufacture of Artificial Fuel, of which the following is a specification:

The invention will first be fully described,

and then pointed out in the claims.

central journals in the sides I) D of the ma chine. The belt is made of wire-cloth or other suitable material, strengthened by one or more ropes, E, of wire or other suitable material, and weighted by a series of iron balls or spheres, F, each consisting of two halves or hemispheres fastened together by a bolt, either a straight bolt, as seen in Fig. 4, or a U-shaped bolt, as seen in Fig. .The former bolt is used when the ball has two ropes passing through it for giving increased strength. The latter or U-shaped bolt is employed when but a single rope is employed; but anyother suitable means may be employed for fastening the halves to gether and keeping them in place. The belt is confined between the hemispheres, as seen in the drawing, and the heads or ends and nuts of the bolts are. sunken in recesses in the balls, so as to form no obstruction as the belt revolves. In the surface or periphery of the rollers O C, over which the belt runs, is made a series of cavities or recesses, H, with which the balls engage, so as to act as cogs to prevent the belt from slipping or to propel the same. 1 is a gear-wheel on the outer end of one of the rollcrs G, which receives motion from the drivingwheel J, to which wheel the motive power is applied to drive the machine. K K are the mold and pressing cylinders, so arranged that the outer surfaces run in contact with each other. These sl irfaces are provided with a series of cavities or recesses, L, which, as the cyl inders revolve, register with each other and form chambers M, of oval or other form. These chambers extend in close proximity the length of the cylinders in regular rows, and the prepared coal-dust is received and compressed therein and delivered onto the revolving belt beneath. The compressingcylinders are re volved by means of the gear-wheels N N, which receive motion from the aforesaid driving-wheel J. These gear-wheels are of uniform size or duplicates of each other and mesh together, so that the compressin g-cylinders revolve with a uniformmotion in opposite directions. 0 is the mixing or pug mill, consisting of an outer casin g, P, and a central vertical shaft, Q, which latter is provided with a series of horizontal knives, which are made adjustable to any desired angle.

The coal-dn st is combined with clay and limewater in suitableproportions, or with any other substance or substances to secure a proper de gree of adhesiveness, and is introduced into the pugmill in a plastic state, and is delivered to the compressing-cylinders in a broad sheet, where it is divided and pressed into blocks or lumps convcnientfor use, and delivered onto the apron and conveyed away to be dried and further prepared ,for use. The thickness of the plastic sheet is regulated by the inclined slides It R, which form together a kind of hop per above the cylinder. These slides are 0perated by means of the lever S S.

The pug-mill is driven by means of gearing actuated by a miter-pinion on the end of the driving-wheel shaft, which pinion revolves a vertical shaft, T, upon the upper end of which is a spur-wheel, U. V is a changeable intermediate spurgcar, which engages with the wheel U, and also with the spur-wheel W on the shaft Q, of the pug-mill. The shaft of this wheel V works in an oblique slot, so that a larger or smaller wheel may be substituted thercfoi for increasing or diminishing the speed of the mill.

The mixin g and prcssin g performed bymeans of this machine is the first operation in the process of preparing artificial fuel from coal-dust, and thereby utilizing the waste products of coal-mines and coal-yards.

Having thus described my invention, I claim and the graduation thereof to be made by the as new and desire to secure by Letters Patsanie means, as set forth.
